The newly described species Crocodylus lucivenator existed 3.4 to 3 million years ago in present-day Ethiopia, and looked similar to the American crocodile (Crocodylus acutus). It’s clear that C. lucivenator was a sizable foe. Apart from the apex predator’s size, C. lucivenator also showcased some unique physical traits. While a similar bony growth can be seen on present-day American crocodiles, they aren’t apparent on Africa’s Nile crocodile (Crocodylus niloticus).C. There is currently no direct fossil evidence of A. afarensis falling victim to an attack by C. lucivenator, but their overlapping timelines mean such scenarios were all-but-inevitable.
